The invention relates to the field of street-crossing early warning methods, in particular to a pedestrian street-crossing early warning method and system based on multi-source information fusion, and the method comprises the steps: recognizing the lane-level signal lamp passing information of a signal machine, and collecting the radar positioning data and image positioning data of a street-crossing target; rTK high-precision positioning is adopted to carry out joint calibration with radar positioning data and image positioning data, and the radar positioning data and the image positioning data are mapped and positioned to a geodetic coordinate system; performing parameterized configuration correction, performing accurate positioning matching and type matching fusion on radar positioning data and image positioning data, and continuously tracking a crossing target based on fused target state information; graded early warning is carried out on crossing targets and vehicles according to an early warning strategy, and the system comprises an industrial personal computer, a radar, a high-resolution camera, an RTK, a signal machine, an RSU, an OBU and pedestrian crossing early warning digital evolution equipment. According to the invention, accurate and timely early warning prompt can be carried out on the actual street crossing condition, and the street crossing and driving safety is improved.
